Charlie Duke (CAPCOM)

Apollo 11, Houston. Say again. Over.

Charlie Duke (CAPCOM)

Apollo 11, Houston. We got a lot of noise on the downlink. Would you please try your high gain in wide beamwidth, and the angles are 180 the yaw and pitch zero. Over.

Michael Collins (CMP)

Houston, Apollo 11. How do you read us on the high gain? Over.

Charlie Duke (CAPCOM)

Roger, Mike. You're a lot better now. Over.

Michael Collins (CMP)

Okay. You want a wide beam for some reason?

Charlie Duke (CAPCOM)

That's affirmative. We got you in the shadows, though. You are looking right down along the engine bell towards the Earth so we need you in wide beam. Over.

Michael Collins (CMP)

Okay. Fine. We're starting our maneuvers to sleep attitude. Roll 82, pitch 229, yaw zero.

Charlie Duke (CAPCOM)

Roger. The angles you got in the flight plan will he good when you get there.

Neil Armstrong (CDR)

Okay. We are on page activation 12 and 13, step 4, and verify descent talkbacks gray, and they're barberpole.

Charlie Duke (CAPCOM)

Apollo 11, Houston. We would like you to take the low voltage taps OFF; RESET, then ON. Over.

Neil Armstrong (CDR)

Stand by. We got it. We just had one circuit breaker out of position.

Buzz Aldrin (LMP)

… should have warmed up by now.

Buzz Aldrin (LMP)

Oh, he's transmitting on B.

Neil Armstrong (CDR)

Hey, Mike, you transmitting on B?

Buzz Aldrin (LMP)

Houston, Apollo 11—Apollo 11/Eagle. Over.

Charlie Duke (CAPCOM)

Roger, Eagle. This is Houston. We read you. Over.

Buzz Aldrin (LMP)

Roger. I read you about four by four. Could you give me a short count, please?

Charlie Duke (CAPCOM)

Roger, Eagle. Coming in with the short count—1, 2, 3, 4, 5; 5, 4, 3, 2, 1. Houston out. Over.

Buzz Aldrin (LMP)

Roger. Are you copying my low bit rate? Over.

Charlie Duke (CAPCOM)

Roger. We got some beautiful data here, Eagle. We're—All those guys are looking at it—systems guys. We'll have some word for you in a minute how everything looks.

Buzz Aldrin (LMP)

Roger. I'm all ready to switch to high bit rate if that's okay with you.

Charlie Duke (CAPCOM)

Would you please stand by, Eagle. We want to get to the proper sleep attitude before we proceed on with the COMM check. Over.

Buzz Aldrin (LMP)

Houston, Eagle. We'll go ahead with the camera checkout. I'm still on low taps, and I assume there's no problem doing that. Over.

Charlie Duke (CAPCOM)

That's affirmative. No problem on that, Eagle. You can go ahead and power up the sequence camera. Over.

Buzz Aldrin (LMP)

Should have done that before.

Charlie Duke (CAPCOM)

Eagle, be advised—sounds like a hot mike. Over.

Buzz Aldrin (LMP)

Roger. If you're reading me now, I am in hot mike because I'm in ICS push to talk, and DOWNVOICE BACKUP. Over.

Charlie Duke (CAPCOM)

Roger. We just wanted to remind you. Over.

Charlie Duke (CAPCOM)

Columbia, this is Houston. Are you maneuvering to sleep attitude? Over.

Charlie Duke (CAPCOM)

Eagle, this is Houston. We have lost all the voice and data with Columbia. Would you see if he is maneuvering to sleep attitude? Over.

Buzz Aldrin (LMP)

Hey, Mike. You maneuvering to sleep attitude?

Buzz Aldrin (LMP)

I don't believe they can hear you, Mike. Are you maneuvering now to sleep attitude?

Buzz Aldrin (LMP)

Houston, Eagle. The Columbia has maneuvered to sleep attitude. He's got the high gain antennas—antenna angles set in, and he should be communicating with you. Over.

Charlie Duke (CAPCOM)

Roger. We don't have him. Stand by.

Charlie Duke (CAPCOM)

Eagle, Houston. Would you please have Columbia put in COMMAND RESET? Over.

Charlie Duke (CAPCOM)

Eagle, Houston. Since we're in sleep attitude, I'll give you another long count. If you're reading in this mode, we'd like you to switch to high bit rate. Over.

Buzz Aldrin (LMP)

Roger. Go ahead with your short count.
